Title: Variable switched capacitor filter
Inventor: NAKAYAMA KENJI
IPC: H03H19/00
Filed: 1982-02-22
Abstract: PURPOSE:To decrease the chip size, by using a variable SCF operated at clock frequencies fs and fs/M and realizing high and low cut-off frequencies respectively. CONSTITUTION:A variable SCF1, H1(Z) of transfer function and a variable SCF2, H2(ZM) of transfer function are connected in cascade. The SCFs 1, 2 are LPFs operated in frequencies fs and fs/M(where; M is a positive integer). In realizing fc1-fc3, the cut-off frequency of the SCF1 is fixed to fc6 and the cut- off frequency of the SCF2 is made variable. Then, in realizing fc4-fc6, a switch 3 is turned on, the SCF2 is bypassd and the SCF1 is exclusively used. Thus, the number of unit capacitors is reduced and the chip size as an integrated circuit is reduced accordingly.

Title: Rotary compressor
Inventor: UMEOKA IKUTOMO
IPC: F04C18/356
Filed: 1990-02-09
Abstract: PURPOSE:To suppress unevenness of an air gap so as to contrive reduction of noise and prevention of motor efficiency decrease by setting a clearance between a shaft and an auxiliary bearing to a minimum oil film thickness in a specific position in an opposite direction of rotation from a vane. CONSTITUTION:A clearance between an auxiliary shaft 3d of a shaft and an auxiliary bearing 10 is set to a minimum oil film thickness H in a position at an angle alpha deg. in an opposite direction of rotation from a vane 6. Refrigerant gas is compressed according to rotation of the shaft. Here a gas pressure load acts on a crank of the shaft to unbalance its rotation, and the auxiliary shaft 3d of the shaft tends to whirl in the direction alpha deg. in the opposite direction of rotation from the vane 6. However, since the above-mentioned clearance is set to the minimum oil film thickness H, deflection of the auxiliary shaft 3d is suppressed by an oil film pressure. In such a way as mentioned, increase of noise and decrease of motor efficiency due to gap unevenness can be prevented.

Abstract: PURPOSE:To eliminate possibility such that printing data is fallen when a printer cover is opened inadvertently during printing, by providing a lock mechanism for limiting the opening and closing of the printer cover to a falt bed type printer. CONSTITUTION:When a current is supplied to a solenoid 19, a movable iron core 20 is attracted and a control lever 16 is moved to a B-direction through a boss 17. Because the arms 16a, 16a of the control lever 16 are respectively penetrated into the leading end part of opening and closing levers 13, 13 by the movement of said lever 16, the opening and closing levers 13, 13 can not rotate even if opening and closing buttons 15, 15 are depressed. Therefore, the engagement of the opening and closing levers 13 and lock shafts 12 are not released and an upper substrate 10 is not opened. Herein, when necessity for opening a printer cover is ganerated, if the supply of current to the solenoid 19 is stopped after a printing stopping button is depressed, the control lever 16 moves to an A- direction by the pulling force of springs 18, 18 and the printer cover can be opened by depressing the opening and closing buttons 15, 15.

Abstract: PURPOSE:To test the capacity type measuring machine accurately at low cost while preventing an error in measurement due to oscillation by calculating the mean value of the weight of the measuring machine, a hopper, and granules in it in a time longer then the oscillation period of an oscillation body and at sufficiently short time intervals. CONSTITUTION:While the rotation of a table feeder 1 is stopped, the weight of the hopper 2 of a load cell 3, granules in it, and the feeder 1 and its mean value w1 are calculated (n) times in the time T longer then the oscillation period t1 of the oscillation body and at the sampling period t2 <=1/10 oscillation period t1 to obtain a real value at the time of no oscillation. Then, the feeder 1 is rotated for confirmation and then stopped to calculate a mean value w2 by repeating the same process. Thus, an error in the measurement of the weight due to the oscillation of the oscillation body is prevented, and the capacity type measuring machine for granules is tested by the inexpensive, simple method.
